I am in exactly the same boat, just replaced my Asics Gt1170s with new Gt1000s with a view to having them ready to wear for VLM, women's 6.5 which I have been wearing for the past 3-4 years are now too small, luckily men's size 6 fit perfectly, but they are so hard underfoot, like there is no cushioning at all and my feet ache after wearing them, done 3 x 5 miles runs now both road and trail and they are no better.
I also got some Mizunos and they are great but I think the asics will have to go back (luckily got them from Sweatshop). Been wearing Asics for years and usually they're good to go pretty well from new but these are like running on cardboard, not nice.
Sorry not much help but reassuring to know it's not just me!
